Index Card RPG

Overview

Index Card RPG (ICRPG) is a universal, fast-paced tabletop role-playing game designed by Brandish Gilhelm (Hankrin Kapuf) and published by Runehammer Games. Originally released in 2017, with its definitive "Master Edition" published in 2021, the system is designed to strip away the mechanical bloat and analysis paralysis often found in traditional d20-based systems. It serves as both a standalone game and a philosophical design toolkit meant to be hacked, modified, and integrated into other role-playing systems.

Description

ICRPG is highly customizable and natively includes multiple distinct settings within its core rulebook, ranging from traditional high fantasy (Alfheim) and gritty sci-fi (Warp Shell) to weird west prehistoric survival (Ghost Mountain). The system treats game mastering as a visible, high-momentum performance. Rather than hiding information behind GM screens, ICRPG brings structural elements, like turn timers, room difficulties, and tracking metrics directly into the open. The game derives its name from the use of standard index cards to abstractly map encounters, represent terrain, track turn order, and quickly visualize items or monsters, eliminating the need for complex grid maps or expensive miniatures.

System Overview & Key Features

The Room Target Instead of assigning different Difficulty Classes (DCs) or Armor Classes (ACs) to every individual object, monster, and trap in an area, the Game Master sets a single "Room Target" number for the entire scene (typically ranging from 10 to 15). Every single d20 roll made by a player in that room, whether it is an attack roll, a saving throw, a stealth check, or an arcane spellcast: must meet or exceed that exact same Target number to succeed. The GM can temporarily adjust this target up or down by 3 points for specific tasks that are explicitly "Easy" or "Hard."
Loot-Based Progression Characters do not possess traditional levels, nor do they gain intrinsic stat increases or health boosts when accumulating experience points. Instead, character progression is entirely physical and external, driven by "Loot." Every class feature, stat modification, magical spell, and unique ability is physically tied to an item equipped on the character sheet. If a character's gear is destroyed, stolen, or voluntarily traded to an ally, their mechanical capabilities shift completely, forcing players to focus on acquiring and managing an inventory limited to 10 carried and 10 equipped items.
Visible Turn Timers To prevent tactical stalling and maintain pacing, the system relies heavily on explicit, visible timers. At the start of an encounter, the Game Master openly rolls a four-sided die (1d4) in front of the players. This represents the number of rounds remaining until a cataclysmic or complicating event occurs, such as a cave-in, the arrival of enemy reinforcements, or a bomb detonating. This mechanic converts passive exploration into an immediate, high-stakes tactical countdown.
Abstract Range Zones Tactical movement completely abandons feet, meters, and grid counting in favor of four abstract distance zones: Close (touching or within arm's reach), Near (a few steps away, reachable within a single move action), Far (within sight and shootable, requiring a full dash to reach), and All the Way (distant or requiring specialized long-range capabilities). Positioning is easily tracked using index cards as relative zone containers.

My name is David and I'm a newbie when it comes to TTRPGs in general, though time playing games (of the video game style) have always been my favorite. I like to collect (and read) TTRPG books/manuals and have read most of the 2014 D&D Player Handbook and significant portions of the DM Guide. I'm also a board game player and collector and I would say that one of the things that entices me to TTRPGs is the social aspect. I would love to have an in person group but would also be good playing online, especially from the ease of getting together. I work from home, have a camera and mic setup, and an accustomed to being on camera and talking in meetings.  Another thing I'm super interested in is just playing a TTRPG in general. I want to create a character, start playing, go on adventures, watch my character and team grow, get some cool weapons and loot, and build memories.  I would prefer fantasy above all else but I'm also interested in the Star Wars universe.

The storyteller Narrative minimalist
Let’s go on an adventure together! I'm looking for a free, cooperative, consent-based, story-focused TTRPG table. I enjoy character-driven games with party relationships, meaningful combat, exploration, mystery, downtime, and earned emotional moments. Ideal balance: about 40% roleplay, 20% combat, 40% exploration. I like sincere games with humor, but not constant bits, edgelord behavior, or main character syndrome. I fit best with players who share spotlight, cooperate, respect boundaries, and care about everyone’s character mattering. Consent and safety are important to me. Heavy themes, PvP, romance/flirting, sexual content, intense character conflict, or major effects on another PC should be discussed first. Lines and veils should be respected. I’m in Hawaiʻi Time / UTC-10. Weekends are best, and I prefer 2–3 hour sessions. I’m open to voice, PBP, or hybrid formats. Not a good fit for bigotry, disruptive rules-lawyering, non-cooperative play, unconsented PvP/romance/sexual content, trauma dumping, or using RPGs as therapy.

Usually behind the screen, always happy to grab a seat and try another system. I bring curiosity, share the spotlight, and work with the GM and fellow players to create the kind of moments you only get around a TTRPG table.

I've been playing for a while, but am really into story games (PbtA, CfB, FitD) these days, but open to just about any TTRPG (mostly Indie, though). I play on the Open Hearth gaming community, and am open to other online games, but am hoping to meet others face to face as well. I'm based in Surrey, but can get up to London reasonably easily. I like embracing Improv, play-to-find-out principles, and prefer games that also do so.

Forged in the Dark (2017)

Forged in the Dark is a tabletop roleplaying game framework and System Reference Document created by John Harper. Released in 2017, it is the underlying engine that powers Blades in the Dark and has since been used by independent designers to build countless other games, such as Scum and Villainy and Band of Blades. It excels at telling stories about capable but flawed groups of people pulling off daring missions against overwhelming odds. The system it directly evolved from is Blades in the Dark Description Instead of being a single game, Forged in the Dark is an open license toolkit. Players form a crew, whether they are space smugglers, military mercenaries, or rebel outcasts, and undertake dangerous missions known as Scores. The system is heavily narrative and focuses on failing forward, meaning a bad dice roll never stalls the story, but instead introduces a new complication. It completely eliminates tedious planning phases by throwing players directly into the action. System Overview & Key Features The d6 Dice Pool To resolve a risky action, a player rolls a pool of six sided dice based on their action rating. The highest single die determines the result. A six is a full success, a four or five is a partial success with a consequence, and a one to three is a bad outcome. Position and Effect Before the dice hit the table, the Game Master establishes the Position (Controlled, Risky, or Desperate) and the Effect (Limited, Standard, or Great). This ensures everyone understands exactly what is at stake and how much impact the action will have. Progress Clocks The game tracks complex threats and long term projects using circular clocks divided into segments. A stealth mission might have a clock for the guards going on high alert, filling up bit by bit as the players roll partial successes or failures. Stress and Resistance Characters have a Stress track that they can spend to push themselves for extra dice or to assist an ally. More importantly, players can spend Stress to resist any consequence the Game Master introduces, allowing characters to survive deadly situations by sheer willpower. Flashbacks Players do not need to spend hours planning a heist or mission. When they encounter an obstacle, they can simply spend Stress to declare a flashback, narrating how their character anticipated the problem and set up a solution in the past. Phases of Play The game flows through specific phases. Free Play is where characters gather information and choose a target. The Score is the actual mission. Finally, Downtime allows the crew to recover from injuries, reduce their heat, and work on personal projects before the cycle begins again.
